Your friend really wants to buy the newest coolest cell phone which will cost him $310 he gets a job detailing cars and suvs and plans to save all the money he earns if he gets paid $60 to detail a car and $85 to detail an suv which of the following inequalities can be used to determine how many of each he must detail in order to earn at least $310

Answers

Answer:

[tex]60c + 85s \geqslant 310[/tex]

Step-by-step explanation:

He needs to earn at least $310 so $60 per car is 60c and $85 per SUV is 85s. So the answer is the third option.

The required inequality:

60x + 85y >= 310

What is inequality?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given, a person gets paid $60 to detail a car and $85 to detail an SUV.

Let's assume he needs to detail x number of cars and y number of SUVs to earn at least $310.

Then, the amount earned by detailing x cars and y SUVs can be expressed as:

60x + 85y

According to the problem statement, he wants to earn at least $310, so we can write the inequality:

60x + 85y >= 310

This is the required inequality to determine the number of cars and SUVs he needs to detail in order to earn at least $310.

Answers

Answer:

x(x + 1)

Step-by-step explanation: This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1)

After a tropical storm in a certain state, news reports indicated that 19 percent of households in the state lost power during the storm. A state engineer believes that estimate is too low. The engineer will collect data to perform a hypothesis test on the proportion of all households without power. Which of the following are the appropriate hypotheses for such a test?

Answers

Answer:

D

Step-by-step explanation:

The null hypothesis is that p=0.19. The engineer says that this estimate is too low, meaning he believes the true proportion is greater than 0.19 - p>0.19. Because this is a proportion of ALL houses in the state, we use p rather than phat, leaving D as the correct answer.

Answers

Given:

Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster.

To find:

The graph that represents the set of heights that satisfy this requirement.

Solution:

Let x be the height required for the ride.

Guests must be at least 54 inches tall to be able to ride the roller coaster. It means required height is greater than or equal to 54.

[tex]x\geq 54[/tex]

So, 54 and all values above 54 are in the solution set.

Since, 54 is included in the solution set, therefore there is a closed circle at 54. All values above 54 are in the solution set, so everything to the right of the circle is shaded.

Therefore, the correct option is C.

You would keep the 7 1/2 and change the divided sign to multiplying sign and flip the 3/4 so its a 4/3 and then multiply it.

15/6 times 4/3. 15 x 4 = 60

The given ratios  5:3 and 6:4 are not equivalent.

What are Equivalent ratios?

Equivalent ratios are the ratios that are the same when we compare them. Example 1/2 and 2/4 are equivalent ratios.

Two or more ratios can be compared with each other to check whether they are equivalent or not.

The given two ratios are 5:3 and 6:4

We can write them as 5/3 and 6/4

Let us apply subtraction, if we get 0 then these are equivalent.

6/4-5/3

The LCM of 4 and 3 is 12

Answers

x² - 10x = -34

x² - 20x + 100 = 66

James is purchasing a new pair of AirPods for $199.99. If the tax rate is 9%, how much will he spend?

Answers

Given:

Price of new AirPods = $199.99

Tax rate = 9%

To find:

How much will he spend?

Solution:

We have,

Price of new AirPods = $199.99

Tax rate = 9%

Tax value = 9% of $199.99

                = [tex]\dfrac{9}{100}\times 199.99[/tex]

                = [tex]17.9991[/tex]

Now,

Total money spend = Price of AirPods + Tax

                                = [tex]199.99+17.9991[/tex]

                                = [tex]217.9891[/tex]

                                [tex]\approx 217.99[/tex]

Therefore, the total money spend by James is $217.99.

Answers

Answer:

(3, - 2 )

Step-by-step explanation:

Given the 2 equations

4x - 2y = 16 → (1)

y = - 5x + 13 → (2)

Substitute y = - 5x + 13 into (1)

4x - 2(- 5x + 13) = 16 ← distribute and simplify left side

4x + 10x - 26 = 16

14x - 26 = 16 ( add 26 to both sides )

14x = 42 ( divide both sides by 14 )

x = 3

Substitute x = 3 into (2) for corresponding value of y

y = - 5(3) + 13 = - 15 + 13 = - 2

solution is (3, - 2 )
